Bang & Olufsen is ready to take full advantage of the new features of Apple's Airplay 2. The high end speaker maker announced they'd work with Apple's audio streaming system in January. After Apple officially launched Airplay 2 on Tuesday, Bang & Olufsen made the integration official Wednesday and announced it would roll out to 10 of the company's speakers starting this August and September.

Airplay has always allowed you to stream audio and video from your iPhone to devices such as your Apple TV and the Apple HomePod smart speaker. Airplay 2 adds the ability to group multiple devices together for synced or stereo playback. If you have two HomePods, you can play a song on both simultaneously and even set the two up to play the song in stereo. Apple's teased the launch of Airplay 2 for awhile, and it finally rolled out Tuesday as part of the launch of the company's newest mobile software iOS 11.4.
